ADJUBTABLE Hun-PLATE.

To all whom it met concern:

Be it known tha t I, CHARLES W.\ ;DAKE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certa1n new and useful Improvement in Ad ustable Hub- Plates,of which the following is a specification.

My invention relates to means for ad usting or taking up, to accommodatefor wear, hub plates particularly of locomotive driving'wheels. Broadlyspeaking it has to do with the adjustment of hub plates-or wearingplatesand it relates to means for mechanlcally advancing 'such plate toaccommodate for-wear. he invention is 1llustrated in the accompanyingdrawings wherein-- Figure 1 is a cross section of the hub, on the linemm of Fig. 3, with my 1mprovements attached;

Fig. 2, an enlarged detail;

Fig. 3, a lan view of the from the hu Fi 4:, 5 and 6, details.

Li 0 parts are indicated by the same let- A is the axle, B the wheelhub, C-the hub plate, D the pinion like end of a p n D having a squaredhead D and a ser1es of surface slots 1) adapted to receive the end D ofthe screw 1) which'is provided with a head D and is screw threaded intoan aperture in the hub. Thehub late 1s provided with the outer flangeand the inner flange C both screw threaded.

E is an outer ring and F, an lnner ring,

plate removed adapted to be received respectively into the I screwthreads of the flanges C and G Each of these rings is provided with anin ternal rack or gear, respectively E and F to receive the pinion likeend D on the pin D I do not wish to be limited to the recise form,structure and arrangement 0 parts shown as my drawings are to be takenas part diagrammatic, although in the main they represent a workingapparatus.

The use and operation of my invention are as follows I s The hub, as forexample, of a locomotive wheel is recessed and into the recess s1nserted the two flanges of the adjustable hub plate. Within the annulusformed by the flanges are placed the two rings wh1ch engage the screwthreads on the inner SldeS 'side in combination Patented Oct. '18, 1921. 1919. Serial No, 312,264. 5

of the flanges. These parts, of course, are in half circles as indicatedby Fig. 3 so that they can be slippedinto position with out removing thewheel from the axle. The pin with the pinion end is inserted through thehole in the hub, until the pinion lies between the two rings and engagestheir respective racks or internal gears. When the pm D is out ofposition, a socket wrench can be applied to the head D and the pin canbe turned on its axis. This will result 111 rotating the two rings andas theyare in screw threaded engagement with the flanges on theadjustable hub plate, they tend to move the ub plate outwardly and thisaffects the desired adjustment uired because of wear on the outside surace of the hub plate. The parts are held in proper position by screwingthe pin D forward so that its end 13* rests in one of the slots D in thebody of the pin D and thus the parts are locked in the desired osition,as for example, in the advance .posltion illustrated in Fig. 2.

I claim:

1. A hub having an annular recess on one with a plate having twointernally threaded flanges, two rings externally threaded to engagesaid threads on the flanges and means for rotating the rings to advancethe plate.

.2. A hub havmg an annular recess on one side in combination with aplate having two internally threaded flanges, two rings externallythreaded to engage said threads on the flanges and means for rotatingthe rings in opgosite direction to advance the plate.

3. hub having an annular recess on one side in combination with a platehaving two internally threaded flanges, two rings, externally threadedto engage said threads on the flanges and means for rotating the ringsto advance the plate, said means including racks on the inside of therings and rotatable means engaged in said racks. 4. A hub having anannular recess 6n one side in combination with a plate having twointernally threaded flanges, two rings externally threaded to en agesaid threads on the flanges and means or rotating the rings in oppositedirection to advance the plate, said means including racks on the insideof the rings and rotatable means engaged in said racks.

5. A hub having an annular recess on one side in combination with aplate having two annular recess on one side, a transverse internallythreaded flanges, two rin s externally threaded to engage said threa son the racks on the inside of the rings and a pinion engaging said racksand means for rotating the pinion.

6. A hub having an annular recess on one side in combination with aplate having two internally threaded flanges, two rings externallythreaded to en age said threads on the flanges and means or rotating therings in opposite direction to advance the plate, said means includinracks on the lnside of the rings and a pinlon engaging said racks andmeans for rotating the pimon.

7. A hub having an annular recess on one side in combination with aplate having two internally threaded flanges, two rings externallythreaded to engage said threads on the flanges and means for rotatin therings 'to advance the plate, and means or lockmg the rotating means 1nposition. v

8.. The combination of a hub, havin aln o e leading into the bottom ofthe annulus and an annular hole connected with the first mentioned hole,with a plate having two internally threaded flanges to be received intothe recess, two rings externally threaded to engage the threads on theflanges and internally racked, a pin in the transverse hole providedwith a pinion to enga e the racks, a head whereby it maybe turne in thesurface recesses, and a second pin screw thread-, ed into the secondhole and provided with a head whereby it may be rotated and an end to bereceived into the recesses in the firstpin to lock it in position.

9. A hub having a bearing surface on one side combination with a platehaving two internally threaded flanges, two rings ex ternally threadedto engage said threads on the flanges and means for rotating the ringsto advance the plate laterally with referencesition, comprising a memberadapted to be advanced on an axis transversal to that of said pinion, toengage-said pinion.

11. A hub having an annular recess on one side in combination with aplate having two internally threaded flanges, two rings ex-' ternallythreaded, to engagesaid threads on the flanges and means for rotatingthe rings in opposite direction to advance the plate saidmeans includingracks on the inside 0 the rings and a PiIllOIl engagingsaid racks andmeans for rotating the pinion, and means for locking the rotatlng meansin position, comprising a screw adapted to be advanced on an axistransverse to that of the pinion, the pinion having about its circumerence, adapted to receive the end of the screw.
